3. Step-by-Step Preparation
1. Roast the Spaghetti Squash:
- Prepare the Squash:
- Preheat oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds.
- Season and Roast:
- Drizzle olive oil over the squash halves and sprinkle with salt and pepper. Place cut-side down on a baking sheet and roast for 35-40 minutes, or until the flesh is tender and easily shredded.
- Cool and Shred:
- Allow the squash to cool slightly, then use a fork to scrape the flesh into spaghetti-like strands. Set aside.
2. Prepare the Sauce:
- Mix the Ingredients:
- In a small bowl, whisk together tamari, peanut butter, rice vinegar, lime juice, brown sugar, sriracha (if using), and water. Adjust consistency as needed.
3. Cook the Stir-Fry:
- Heat the Oil:
- In a large skillet or wok, heat sesame oil over medium heat. Add minced garlic and sauté until fragrant, about 1 minute.
- Add Vegetables:
- Stir in bell peppers, carrots, and bean sprouts. Cook for 3-4 minutes until just tender.
- Cook the Eggs:
- Push the vegetables to one side of the skillet. Pour the beaten eggs into the empty side and scramble until cooked through. Mix the eggs with the vegetables.
4. Combine the Dish:
